To aZZ whom it may concern.-

Be it known that I, SAMUEL S. HEPWORTH, a resident of Yonkers,Westchester county, in the State of New York, have invented cer tain newand usefullmprovements in Gentrifugal Machines for Steaming Sugar, ofwhich the following is a specification, reference being had totheaccompan ying drawings, in which Figure l is a vertical section of acentrifugal machine embodying my invention; section on line 11 of Fig.2. Fig. 2 isasection partly broken away on line 2-2 of Fig. 1, lookingin the direction of the arrow. Fig. 3 is a sectional detail of amodified form in which the fan-blades are shown, and Fig. 4 is an underside detail view of the sectional bottom, clearly showing thesefan-blades.

My present invention relates to centrifugal machines and has for itsobject to enable such machines to be used for steaming sugar.

To this end my invention consists in placing an adjustable ring in thecurb of the machine, in proximity to the bottom of the basket in orderto force the steam to surround and enter the basket. I

In the drawings, A is the curb of the machine provided with a cover B inwhich there are two openings closed by lids 0. and b. Mounted on thespindle 0 within the curb, is the basket D. The bottom of this basket isformed partly by the annular flanged plate E, partly by the sectionalbottom 0 d eriveted thereto, and partly by the Wings fof the valve F,when the latter is-turned to cover the apertures, as shown in Fig. 1,and in dotted lines in Fig. 2. The spindle O is stepped in bearings G,and serves to rotate the basket D. Mounted on the curb ring A is thering H supported on set-screws h or other analogous devices, so as to beadjustable on the curb ring to and from the bottom of the basket. Arubber ring or other suitable packing g between the ring H and the curbring renders the joint steam tight. The ring H is designed to preventthe escape of steam from the curb into the central area K, and to forcethe steam to surround and enter the basket. To this end the ring H isbrought up into close proximity to the bottom of the basket, but isnever allowed to touch it. This ring Hobviously may be mounted so as tobe embraced by the curb ring A.

There is at all times a space of about one quarter of an inch betweenthe top of the ring H and the bottom of the basket. During rapidrotation of the basket, airis forced into the curb from the area K, at asufficient pressure to prevent the escape of steam between the ring Handthe bottom of the basket. If it be found necessary, fans maybe providedon the rotating parts to keep up this air pressure, as shown in Figs. 3and 4 but for ordinary steam pressures, they will not be required.

Steam is supplied to the apparatus by the supply-pipe S, and togetherwith the sirup and other by-products is exhausted at L.

The basket is filled with masse cuite through the opening at b, andafter it has been drained and steamed, the lid a is removed and thesugar is discharged through the bottom of the basket by turning thevalve F. During steaming, both lids a and b are in place, and the steambeing unable to escape except at L, is forced to surround and enter thebasket to effect thorough steaming of the product.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1S

. 1. In a centrifugal machine, the combination with an outer casing ofmeans for ad mitting steam to said casing, a basket D, a curb ring A inproximity thereto, and a ring H mounted on the curb ring serving toconfine the steam within the curb, and easing, substantially asdescribed.

2. In a centrifugal machine, the combination with an outer casing andmeans for admitting steam to said casing, of a basket, a curb ring inproximity thereto, and a ring H mounted on the curb ring, and casing,and means outside of the casing for adjusting said first named ring toand from the bottom of the basket, substantially as described.

3. In a centrifugal machine, the combination of an outer casing, meansfor supplying steam to said casing, a basket, a curb ring in proximitythereto, a ring H mounted on the curbring, and means for adjusting saidfirst means for adjusting said first mentioned ring l0 from outside thecasing, and fans mounted on the basket and operating in the area,substantially as and for the purposes specified.
